Here is the actual section of the by-laws that have been in them forever. It was thought that since the meetings are "open" (also attached) that general attendees to the meeting can vote. If they can't vote, can they participate in discussions?
SECTION 2. Any member in attendance at a senior center meeting shall have the right to participate in that meeting and shall have the right to vote so long as the person is a member in good standing prior to any vote being taken.
SECTION 1. All meetings of the organization or its Board shall be open meetings and held during daylight hours.
